Checked it out. Definitely good news. However, bestseller prices are 11.99 instead of 9.99 as in the US, so I suspect other prices will be higher, too. On the other hand, that may be because of higher 3G delivery costs. And you probably couldn't register the Kindle to take advantage of US prices.

And, of course, the selection for non-US customers is more limited than for American customers - I've spotted some books which are available for Americans but not for Germans.
